You don't say what for - annual servicing of outdoor unit, cleaning and disinfecting evaporator coil, adding coolant, or what.

Per unit - minimum annual service ("well" unit servicing) commonly about $50-100 on off-season specials ormore like $100-250 during leak cooling season, coil cleaning commonly $100-150 off-season or $150-250 peak season for many unit brands - though some that are not easy to pull out or do not have isolation valves so require discharging the entire system to remove the gas and to disconnect them from the piping (with subsequent refilling with the evacuated gas and follow-on testing for proper operating pressure and conditions) can run into the $250-500 range commonly.

Of course, your locale, brand of unit, type of setup, ease of access, local competition, etc all make a difference in your cost, as can local competitive range - which can be around 50-100% variation between vendors for routine service, and whilethe most expensive does not ensure the best job, rarely are the lowest third to half anywhere near the best either - with exceptions of course.

My recommendation - find a good, well-rated and reviewed Heating and A/C company (your Search the List category) which does a good job at a fair, not cheapest, price - then stay with them as long as they continue to give good service. Having a good "go-to" electrician, plumber, and HVAC guy can not only give you peace of mind, but as they start to recognize you as a regular customer can pay off in the long run by them making a point of giving you a good deal anytime they can - which might be a break on parts, a free upgrade of some sort, not charging for the full time they are there, or whatever. A good working relationship with a fair and competent provider is worth its weight in gold over the long haul.
